Allow signed in users to submit forms - WordPress

I have been searching for a plugin that allows users to register on a WordPress site and then submit forms so that admin can view it. I have found plugins for user registration and to submit form separately. But how can i combine those functionalities? Or is there a plugin that allows users to register, sign in and submit form?

Only signed in users can submit form and the form must be customizable.
